The dungeon is quite deep, from what I'm inferring. Most of two stories in wouldn't show off very much of it at all, and the increased presence of enemies and traps lower down would serve as a [i]serious[/i] reason to keep Fieri confined to the upper floors. This dungeon's been raided several times over, there can't be anything [i]immensely[/i] dangerous in the lobby and basement. The sub-basements, however... [i]those[/i] house the nasty gribblies.
